2 Claims.

This invention relates to a ring catch particularly applicable as animproved fastening for doors to electrical cutout boxes and other metalclosures.

It isan object of this invention to provide an improved catch and onewhich may be assembled with ease and at the same time provide anefficient catch for small doors. advantages will appear from thefollowing detailed description and from the accompanying drawing.

In the drawing Fig. 1 is a side View of the ring catch before it isapplied to the door.

Fig. 2 is a front View of the catch and ring shown in Fig. 1.

Fig. 3 is a plan view of the ring catch applied to a door.

Fig. 4 is a view taken along line 4-4 of Fig. 3. Numeral 10 indicatesthe ring portion of the catch which serves as a convenienthandle withwhich to open the door of the closure to which the catch is applied.Numeral l2 indicates a portion of the door to which the ring catch isapplied and I4 is a portion of the closure to which the door 12 isapplied. l6 indicates the catch portion and may be formed of a fiatsteel spring of substantially the shape shown. Ear portions iii are bentup and project through openings 20 in the door. When the catch isassembled the ring l extends through openings 2| in the ears [8 and thussecures the catch member to the door without additional securing means.A lip 24 may be bent out from the closure member to engage the catchportion 22 of the catch member I6 and thus holds the door in closedposition. The end of the catch member opposite the portion 22 is bent upas shown in Fig. 1, to engage the inside of the door. This prevents thelatch member from wobbling and causes the ring to bear against theoutside of the door. This makes it possible to use various gauge steelsfor the door with the same catch member.

It can be seen that the chief advantages of this ring catch reside inits ease of assembly and sim- Further objects and It is not necessarythat screws is only plicity of parts. or other fastening means be usedand it necessary to form two parts and two'openings in the door toprovide a complete catch.

Iclaim:

1. A catch assembly for the door of a closure comprising a catch memberand a ring, said catch member being a strip of resilient material havinga concave formed portion with its concave side against the door andhaving a free end provided with a formed bump adapted to enga e a lipextending from the closure to hold the door in closed position, a pairof opposed openings in the door, a pair of opposed ears bent out fromthe flat strip at substantially the center of the concave portion andextending through the openings, said ears provided with openingstherethrough, said ring being adapted to serve as a handle for the doorand extending through the openings in the ears, said ring being adaptedto prevent displacement of the ears from the openings, the concaveportion of the catch member being adapted to maintain the ring againstthe front of the door independently of variations in the thickness ofthe door.

2. In a metallic enclosure for electrical apparatus having a door, aring catch assembly for said door comprising a catch member of resilientstrip material having a concave portion and positioned with the concaveside of said portion adjacent the underside of the door, said striphaving a free end formed with a bump adapted to engage a lip extendingfrom the closure, the door of the enclosure being provided with a pairof 0D- posed slots therethrough, the catch member being provided withtwo upstanding ears located substantially at the center of the concaveportion and extending through the slots in the door, said ears providedwith openings therethrough, a split ring adapted to serve as a handlefor said door extending through the openings in the ears, the concaveportion of the resilient strip being adapted to pull the ring memberdown against the outer surface of the door.
